Hi all,

I have a simple script:

#!/usr/bin/perl -w
use strict;
use warnings;

opendir (DIR, "/some/path");
my @array = readdir(DIR);
closedir (DIR);

my $size = @array;
print "number of files: " . $size-2 . "\n";


it will return:
Argument "size - 2: 4" isn't numeric in subtraction (-) at test.pl line 11. -2


Could someone explain? I thought PERL does not care if the variable is a string or numeric.
Assuming that there are only files in the directory (directory does not contain sub-directory), and since there are two files in that directory, I was expecting the result to print "number of files: 2" (the two files, minus the . and .. values).

TIA
